Python script avoid quitting when Ctrl-C is pressed

Question

I'm trying to run WifiPhisher for educational purposes. At one step it says Press Ctrl-C to input a number. Now when I press Ctrl-c the script exits as I described it in this issue on github. Whereas ideally, the script shouldn't exit rather it should continue the logic after Ctrl-C is pressed. I'm not familiar with Python, can anyone help me get past this?

You can set a signal handler to CTRL-C signal to shutdown the default signal handler which raises a KeyboardInterrupt exception.

import signal, os

def handler(signum, frame):
    print 'Signal handler called with signal', signum

# Set the signal handler
signal.signal(signal.SIGINT, handler)

Ctrl-C (in older Unixes, DEL) sends an INT signal (SIGINT); by default, this causes the process to terminate

SIGINT The SIGINT signal is sent to a process by its controlling terminal when a user wishes to interrupt the process. This is typically initiated by pressing Control-C, but on some systems, the "delete" character or "break" key can be used.[6]
